Knowing exactly when a radiation frost even is occurring allows you to activate frost protection equipment in time to protect your crops and eliminates starting frost protection too early, which wastes money.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMonitor Radiation Frost Events\u003c\/strong\u003e\u003cbr\u003eOn calm, clear nights surface temperature, including leaf and bud temperatures, can drop well below air temperature due to a net loss of longwave radiation to the clear sky. A radiation frost occurs when frost forms at the surface before the air temperature reaches freezing (0 C). Under cloudy and\/or windy conditions, radiation frost events do not occur. The Apogee radiation frost detector is a combination of two high accuracy thermistors mounted in a single housing. One sensor is designed to mimic a leaf and sensor is designed to mimic a bud, providing estimates of leaf and bud temperatures and a direct means of monitoring radiation frost events.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWide Range, Accurate Measurements\u003c\/strong\u003e\u003cbr\u003eThermistor accuracy is ± 0.1 C across a range of 0 to 70 C, providing accurate measurements at temperatures near zero where frost damage is likely to occur.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe MQ-500 is used to measure incoming PPFD measurements in outdoor environments, greenhouses, growth chambers, and aquariums.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003cbr\u003eApplications include leaf and bud temperature estimates in cropped fields, orchards, and vineyards.
